dumpk2

Description

Periodically writes two orchestra control-signal values to a named external file in a specific format.

Syntax

dumpk2 ksig1, ksig2, ifilname, iformat, iprd

Initialization

ifilname -- character string (in double quotes, spaces permitted) denoting the external file name. May either be a full path name with target directory specified or a simple filename to be created within the current directory

iformat -- specifies the output data format:

1 = 8-bit signed char(high order 8 bits of a 16-bit integer

4 = 16-bit short integers

5 = 32-bit long integers

6 = 32-bit floats

7 = ASCII long integers

8 = ASCII floats (2 decimal places)

Note that A-law and U-law output are not available, and that all formats except the last two are binary. The output file contains no header information.

iprd -- the period of ksig output in seconds, rounded to the nearest orchestra control period. A value of 0 implies one control period (the enforced minimum), which will create an output file sampled at the orchestra control rate.

Performance

ksig1, ksig2 -- control-rate signals.

This opcode allows two generated control signal values to be saved in a named external file. The file contains no self-defining header information. But it contains a regularly sampled time series, suitable for later input or analysis. There may be any number of dumpk2 opcodes in an instrument or orchestra but each must write to a different file.
